Life Sack Can Carry Food And Purify Water For Third-World Countries

One of the biggest problems in many parts of the world is the scarcity of clean water. There have been plenty of solutions proposed--from slow-working tablets to UV water bottles--but most are either too impractical or too expensive to be a long-term solution. Enter the Life Sack.

This solar powered water purification system uses UV-A radiation and a thermal treatment process to create clean drinking water. The sack itself is not unlike those used for donating grains and other foods to third-world countries, which means it can serve a dual purpose: initially used to hold donated foods, once those foods are stored away it can then go on being a water purification system. It's also extremely portable, with straps that allow it to be carried around like a backpack.

The Life Sack is the creation of Korean designers Jung Uk Park, Myeong Hoon Lee, and Dae Youl Lee.
